1) Consistency - hopefully playing more and shortening my swing a bit will help with this. The main idea is to get more in touch with my swing, so I can regain fuller control and feel of how to shape every shot I hit.
2) Short game - I long for the days as a teenager when I fearlessly attempted any shot based solely on feel, and usually pulled it off. Technical thoughts have muddied up that feel and made me play a bit more safely, and as a result my short game enjoyment and success have suffered. The course I'm on this year will put a premium on it and hopefully I'll respond!
3) Better management - I think most people who enjoy the study of course architecture generally employ better course management than the average golfer. However I too often fall into the camp of the tempted and get fooled by things I shouldn't, and as a result this season I want to focus on engaging the golf course a bit better and work more on my game's relationship with the features I deal with on each shot. This should help my score a bit but primarily give me a more thorough enjoyment of each round.
The bottom line is to have even more fun and shoot some better scores as a byproduct.
